Email Forwarding

Emails to @oftc.net addresses go through a LDAP distributed email system. This system uses the forwarding field in the LDAP directory to route mail without passing it through a users .forward file on a single host. Multiple machines participate in the forwarding to provide redundancy.

Each forwarders inspects the LDAP database to see if foo@oftc.net has forwarding set to an address, if so the envelope to address is rewritten and the message redirected to the new address.

All machines also use the forwarding attribute as a default destination for email. If the user has a home directory and no .forward file the mail is forwarded rather than delivered to /var/spool/mail. This makes sure cron reports, bug responses and other unexpected emails are not misplaced.

The email forwarding can be easily reconfigured using GnuPG:

echo "emailforward: foo@bar.com" | gpg --clearsign | mail change@db.oftc.net

or by visiting db.oftc.net
